DEVICE FOR FORMING BELT-LACINGS.

SPECIFICATION forming part of Letters Patent No. 612,070, dated October11, 1898.

Application filed ll/Iarch 21, 1898.

To all whom it may concern:

Be it known that I, LEONARD VYNE, a citizen of the United States,residing at North Wilkesborough, in the county of Vilkes and State ofNorth Carolina, have invented a new and useful Wire-Forming Tool, ofwhich the following is a specification.

My invention relates to wire-Working tools, and particularly to a deviceadapted for use in forming belt-lacings designed for connecting theextremities of a flexible driving or other belt; and the object in viewis to provide a simple andefficient device for facilitating the formingor bending of awire to form a lacing suitable for application to a belt.

Further objects and advantages of this invention will appear in thefollowing descrip' tion, and the novel features thereof will beparticularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a forming-toolconstructed in accordance with my invention. Fig. 2 is a detail planview of a portion of the tool, partly in section. Fig. 3 is a verticalsection of the same, taken in the plane of one of the adjusting-bolts.Fig. 4 is a plan view of a portion of a lacing formed by, means of atool constructed in accordance with my invention. Fig. 5 is a detailview in perspective of one end of the lacing.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

Upon a suitable supporting frame or bar 1. are arranged spacedforming-tongues 2 and 3, the tongues 2 being of hollow or loopedconstruction, constituting eyes, and being arranged in an alined seriesat an interval from the flat alined tongues 3, the interval between saidseries of tongues being suitable to the length of the loops 4 in abelt-lacing to be formed thereon. In order that the spaced series oftongues may be adjustable, to enable lacings having loops of differentlengths to be formed thereon, I preferably construct each series oftongues upon a carrier mounted upon the supporting frame or bar, and inthe construction illustrated the carriers of the tongues 2 and 3respectively consist of plates 5 and 6, held to the supporting frame orbar by means of bolts 7. Obviously the bolts,

which in the construction illustrated constitute the adjusting devicesfor the tongue carriers or holders, may be variously constructed toattain the desired facility of adjustment; but for ordinary purp'oseslhave found it sufficient to extend bolts, as illustrated, through thesupporting bar or frame and employ fastening plates or washers S,removably interposed between the bar or frame and the carriers orholding-plates, whereby one or more may be applied or removed to disposethe tongues as required.

In the preferred construction'of the looped or saddle plate 5 it isfolded upon itself upon a longitudinal line to form an inner main fold,which is engaged by the above-mentioned securing-bolt 7, and an outernarrow fold, which is arranged near its lower edge in contact with theexterior surface of the main fold, but is not caught by thesecuringbolt. This enables the outer or narrow fold to yield to avoidcramping the pattern-rod and also provides for spreading the alinedseats or loops formed by the tongues of the plate 5 to accommodatepattern-rods of different diameters.

In operation the wire blank which is to form the lacing is carried backand forth between the tongues 2 and 3 to form a series of narrow loops4, a locking-pin 9 being threaded through the tongues 2 as theweavingoperation progresses. For instance, starting at one end of the tool, as,disclosed in the drawings, the web wire or blank is constructed to forma terminal loop 4:", the extremity of the blank being arranged in theinterval between the terminal tongue 3 and the adjacent tongue, afterwhich the body portion of the wire is carried through the same intervalacross to the interval between the terminal and contiguous tongues 2, isengaged with the locking-pin 9, is carried back and through the sameinterval between the tongues 3, is thence extended longitudinally of themachine at the outer side of the second tongue 3 and again laterallythrough the interval between the second and third tongues 3 and acrossto the opposite or registering interval between the second and thirdtongues 2, and again engaged with the locking-pin, which has beenadvanced longitudinally through the bores of the tongues 2 in order tointersect said interval. This operation is continued to produce a lacingof sufficient length to suit the width of the belt of which theextremities are to be connected. The locking-pin is advanced through theseats formed by the registering openings in the tongues 2 as the lacingof the wire blank proceeds, said blank being carried through the properinterval between two contiguous tongues 2, the locking-pin then beingadvanced to span said interval, and the blank being then foldedbackwardly over the locking-pin to form a loo i.

The simplicity of the apparatus as above described is obvious, and itwill be understood that various changes in the form, proportion, and theminor details of construction may be resorted to Without departing fromthe spirit or sacrificing any of the advantages of this invention.

Having described my invention, What I claim is- A crimper for wirelacing having a parallel sided support, front and rear plates secured tothe opposite surfaces of the support and detachably secured thereto bycommon bolts, said plates being arranged to project above the upper edgeof the support and being kerfed to form parallel spaced series oftongues, and one of the plates being folded upon a longitudinal line toform a series of alined seats or loops, and having its inner plateengaged by said bolts and an outer narrow fold which is free to movetoward and from the plane of the inner fold, and a pattern-rod to fit insaid alined seats or loops, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

LEONARD VYNE.
